This module is a constant life saver for the reporting with not a lot of volume of treatment.

Now if you want to design pure pdf reports, qweb is the standard way to go. Other than that you can chose:

- Aeroo (AFAIK, installation is tricky),

- jasper report or pentaho report (probably more technical but more solid, more professional and a good investment on the long run).

- Webkit is still a good option as well but technically very close to qweb so I'd rather advice the standard approach (I have not heard of any specific advantage of webkit over qweb but there is a good deal of existing reports in that techno. Supported by the OCA.

There are some other exotic solutions but I would not care about them (few support and probably difficult to maintain)
